About ruscal

ruscal syncs your local Outlook calendar (read via MAPI) to a Google
Calendar of your choice. Events appear in the Google calendar with the
organiser surfaced in the description, recurring series expanded, and
cancelled occurrences mirrored — so you stop missing meetings on
whatever device your Google calendar is on.

What's new in 1.2.3

  • docs(readme): note that ruscal requires Outlook Classic (new Outlook has no MAPI)
  • ci: static-link the MSVC C runtime so the binary runs without VCRedist
  • ci: auto-patch Architecture x86->x64 after winget-releaser fires
